Pick Carefully: Getting Airflow in Pick Modules

PICK CAREFULLY:
GETTING AIRFLOW IN PICK MODULES

Walk into any large distribution center and you’ll notice one thing right away: scores of multilevel pick modules. These configurations allow for quick movement of material from shelf to shipping. However, like any other workspace, these areas are in desperate need of air movement. But, with such a small area, is meaningful airflow even possible? Why, yes… yes, it is! I implore you to read on!

Pick modules need air moved quickly from one end to the other. Proper airflow also ensures all aisles are moving air in the same direction. This direction should take into account any large, wall-mounted supply and exhaust fans that may be present (always want to accelerate air from supply to exhaust). Fans at the end of the aisles can be turned sideways – helping to generate airflow around the pick module’s perimeter.

With these airflow parameters in mind, high velocity rack mount fans offer the best solution. No other fan is going to provide the velocity and throw distance needed to effectively move the stagnant air of a pick module aisle. And if noise or headroom is an issue, take a look at Patterson’s DB fan, specifically designed with pick modules in mind. The DB delivers quiet performance and a lower profile, perfect for this unique type of workspace.

So how many fans, and what size should they be? The answer depends on a number of factors. First, fans should be sized such that they do not interfere with everyday work activity (sizing rules do not apply to the DB fan). Then, space your fans such that one fan accelerates the air from its predecessor in the aisle. A good rule of thumb is to place the next fan when the previous fan’s airspeed slows to 2-3 mph. Fan size (air throw distance) and aisle length (fan spacing) will determine the optimum number of fans per aisle.
